Future of AI is Biological

Today we think of Artificial Intelligence(AI) as machines, robots, and software code. Will it be the same or change to become biological artifacts? The journey in AI so far while being inspired by the human brain is diverging from it and increasingly looks unsustainable. Unsustainable energy & data consumption to differences in representation compared to the brain's cortex and learning bottlenecks make a case for promising stem cell-based neural networks. Just hogs too much energy: Machines based AI can compute faster but just hog too much energy to do that.
